Actually, the recommended hook to use for copyright-update nowadays is
not write-file-hooks (which has been marked obsolete since Emacs-22.1)
but before-save-hook.
So it should maybe bind write-file-functions, write-contents-functions,
and before-save-hook, or and maybe after-save-hook as well.

Or maybe a better way would be to use write-region rather than save-buffer.
